Hairong Kuang commented on HADOOP-2757:
---------------------------------------

> In the case when all the datanode(s) in a pipeline go down but the namenode is alive, the close still hangs. is this the case you are referring to?
Yes, if the dfs client hang is caused by down datanodes, then HADOOP-4703 should fix the problem. Could you please doublecheck if this is true?

> Currently {{DFSOutputStream.close()}} waits for ever if Namenode keeps throwing {{NotYetReplicated}} exception, for whatever reason. Its pretty annoying for a user. Shoud the loop inside close have a timeout? If so how much? It could probably something like 10 minutes.
